It integrates two 22 kΩ resistors — one in series with the base (R1) and one between base and emitter (R2) — which eliminates the need for external bias resistors in digital switching and driver stages. Rated for a collector current of 100 mA and a collector-emitter breakdown voltage of 50 V, with a maximum power dissipation of 200 mW. The transition frequency of 200 MHz supports switching applications up to the low-MHz range, such as relay drivers, solenoid drivers, and logic-level translators. The SOT-23-3 package (PG-SOT23-3-1) is a standard surface-mount footprint, suitable for automated assembly and space-constrained PCB layouts. ## Selection check: current, voltage, and saturation The 100 mA collector current rating sets the load ceiling — if the driven relay or solenoid coil draws more than 80 mA continuous, budget for derating or step up to a higher-current device. The 50 V Vceo covers 12 V and 24 V automotive rails with margin, but verify against load-dump transients if the transistor is directly exposed to the battery line. DC current gain (hFE) is a minimum of 50 at 5 mA collector current and 5 V Vce. This is typical for a pre-biased transistor and sufficient to saturate the device with a 500 µA base drive from a microcontroller GPIO or logic gate. ## Automotive qualification and lifecycle This qualification covers temperature cycling, high-temperature reverse bias, and other reliability tests required for production vehicle electronics.","metaTitle":"Infineon BCR191E6327 PNP Pre-Biased Transistor, AEC-Q101","metaDescription":"Infineon BCR191E6327 PNP pre-biased transistor, AEC-Q101 qualified for automotive. 200 mW, 100 mA Ic, 50 V Vceo, 200 MHz ft.
